it's not the length of the contract, it's not even the cost. last season's rabiot for 10m per season is obviously an acceptable cost in today's football.
it's - like b81 said - sending the wrong message, and offering more than the richest epl clubs. both are stupid. it fits the terrible trend of jj offering the highest wages for players who wouldn't get nowhere near that amount elsewhere, see de sciglio, alex sandro, tek, bonucci, rugani, arthur, and even dybala before we turned our attention to vlahovic. we tried to offload mds for years, his contract expires, we offer him an extension, he miraculously gets injured, who would have thought. we extend rugani's contract twice during the same season, he gets a lifetime contract, can't be unloaded. lowest revenue jj of the last decade offers more to unpredictable rabiot than clubs of the richest ever league. you get the drill.
